ADJUSTABLE CURVE FOR STORE- SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 551,624, dated December17, 1895.

Application filed April 25, 1895. Serial No. 547,066. (No model.)

To aZZ whom it may concern.-

Be it known that we, SAMUEL R. GAYTON, of Philadelphia, county ofPhiladelphia, and State of Pennsylvania, and JAMES T. Cow- LEY, ofLowell, county of Middlesex, and State of Massachusetts, have inventednew and useful Improvements in Adjustable Curves for Store-ServiceApparatus; and we hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same.

Our invention relates to new and useful improvements in adjustablecurves for storeservice apparatus; and it has for its object to providea curve that can be readily adjusted to different radii and firmly fixedin that position. I

Often in running lines between two terminals it is necessary that thelines should pass around some obstruct-ion that would prevent aline frombeing run direct between the two points, and in that case it would benecessary to construct a curve which would carry the line out of adirect line to pass around the said obstruction. In some cases it wouldbe necessary to only change the line from a direct line slightly, whilein others it would be necessary to run it at a right angle or even more;and the object of this invention is to provide a curve that can beadjusted by the workman erecting the line, who can readily change theradii of the curve and fix the same for the particular requirements ofthe line he may be erecting. These curves can all be manufactured thesame and can be changed to suit the particular requirements neededwithout any additional labor being expended in erecting, and therebyavoiding the necessity for constructing particular curves for particularcircumstances, as each curve can bechanged by the workman to meet anycondition; and a further object is to provide means for guiding andsteadying the carrier while passing around said curves.

- Our invention consists of certain novel fea- 4 tures, arrangements,and combinations here- In the drawings accompanying this application andwhich illustrate a construction embodying our invention, Figure 1 is aplan view of the curve and carrier together. Fig. 2 is a side elevationof the curve and carrier together. Fig. 3 is an enlarged detail viewshowing in plan and part section a portion of the curve. Fig. 4c is anenlarged detail end sectional view of a portion of the curve. Fig. 5 isan end view in elevation showing the carrier located on the curve. Figs.6, 7, and 8 are detail views of the parts which compose the curve.

Like letters of reference refer to like parts throughout the severalviews.

Upon the standard A there is mounted an arm B, having a hub B aroundsaid standard and secured thereon at any desired position by theset-screw B To the outer end of said arm there is secured an adjustablecurve C, which consists of an eye D, formed on the inner edge of thesheet-metal web E, and through this eye the track-wire D passes. Thissheet-metal web E consists of a series of horizontal sections E, withvertical extensions F, and between each two sections there is a slot Gto permit the eye D to readily bend to any desired radius. On the outerside of the vertical extensions F there is located a flat plate H, andon the inner side of said vertical extensions F there is provided a flatplate J, and the outer flat plate II is provided with a series of slotsH, which register with the slots G in the Vertical extensions F and theslots J in the inner flat plate J, and through these slots bolts K pass,with nuts K on the inner edge, and provided with washers K which bearagainst the inner flat plate J.

When the lineman is erecting the line he determines at what angle hiscurve should be placed, and first loosens the nuts K, which leaves theflat plates II and J loose, and the eye D, through which the wirepasses, can then be sprung to any desired curve. After the eye D is setto the desired curve the nuts K on the bolts K are again tightened,which, by clamping the plates H and J onto the vertical extensions F ofthe sheetmetal web E, firmly holds the eye D to the radius at which ithas been set. Upon the same standard A and below the arm 1- there isarranged an arm L, having a hub L around said standard and adj ustablysecured thereto in any desired position by a set-screw L 011 the outerend of said arm L there is arranged a bracket L having a hub L, providedwith a set-screw If, by which said hub can be set on the arm in anydesired position. At the extreme end of the bracket L there is a foot L,to which is secured the curved guide L against which the roller M,pivotally secured to the bottom of the carrier M bya stud M, works asthe wheels H" of the carrier travel along the eye D of the adjustablecurve, and in this manner steady and guide the carrier in its movementaround the curve.

\Ve do not limit ourselves to the arrange ment and construction shown,as the same may be varied without departing from the spirit of ourinvention, and we further do not limit ourselves to the use of saidcurves in store-service apparatus, as it is equally well adapted forother apparatuses in which adjustablc curves are required.

Having thus ascertained the nature of our invention and set forth aconstruction embodying the same, what we claim as new,

and desire to secure by Letters Patent of the United States, is

1. In a store service apparatus, a way, a carrier adapted to travel 011said way, a curve to which said way is connected capable of adjustmentto diiierent angles, and means for varying the angle of said curve.

2. Ina store service apparatus, a way, a carrier adapted to travel 011said way, a curve to which said way is connected capable of adjustmentto different angles, means for varying the angle of said curve, an armfor suprier adapted to travel on said way, a curve to which said way isconnected capable of adjustment to diilierent angles, an adjustableguide located below said curve, and a roller mounted on the bottom ofsaid carrier and adapted to contact with and be guided by said guide asthe carrier moves around the said curve.

In a store service apparatus, a way, a carrier adapted to travel on saidway, a curve to which said way is connected capable of adjustment todiiferent angles, and means for varying the angle of said curve, thesaid curve consisting of a slotted web and one or more plates to whichsaid web is secured.

In testimony whereof we have signed our names to this specification, inthe presence of two subscribing witnesses, on the 12th and 13th days ofApril, 1895.
